1. NO BLATANT PIRACY. This includes reproducing homebrew less than 10 years old, with the exception of free software.2. No advertising your reproductions, with the exception of free software.3. Be nice. See RFC 1855 if you aren't sure what this means.

I see lot of people put effort into canibalizing more or less valuable games in order to make repro.So when creating my flash-cart Krzysiocart I projected the PCB in that way that it wil be able to mimic almost any mapper - not only popular ones like MMC1/MMC3, VRC, FME7, UNROM/ANROM/CNROM, Mapper 90, but even rare ones that are use for one-titles, multicarts, etc.

Currently not supported ones are MMC2 and MMC5 (but if you don't want to use extended MMC5 features like EX-RAM or Fill mode nametable, it will work).

Firstly, I was developing in on my own home-made etched PCBs, but later I switched into proffesional ones. There is also shell included.

This board has 4 Mbit CHR RAM. This is bigger than the biggest CHR ROM in a licensed NES game or licensed non-MMC5 Famicom game (Kirby's Adventure), and it's as big as the biggest CHR ROM in a licensed Famicom game (Metal Slader Glory) or unlicensed NES game (Action 52). What cart other than a pirate multi has CHR ROM bigger than 4 Mbit?

If your game uses CHR-ROM, you program PRG-FLASH with PRG-ROM + CHR-ROM and then during startup copy CHR-ROM data from flash into RAM. But all of this is done automatically. You just put your ROM into micro sd card and then select it from menu (if you remove SD card, last chosen game will be started automatically).

Does it run some code before executing the user ROM if booted without an SD card? (This matters for some test ROMs which assume that no extra instructions were executed before starting the ROM.)

Mr 6502 is not fortune-teller and it needs to send some commands to SD card to check if it responds or not.But just after run, cartridge starts in NROM mode so you can program it (using Kazzo) to execute your own NROM code.

Are you going to make the CPLD configuration files available so users can reprogram the CPLD to any mapper?

I can make public pin assignments, schematics so everyone interested can program its own mapper, but I'd rather not publish my binaries for CPLD.

I still don't understand what exactly this product is and who the target audience for it is. Is it like a PowerPak/EverDrive but with a hardwired mapper? Can the mapper configuration be easily changed?
